To all ro/zioni, t may concern:

:le itknown that l, SAMUEL B. Berni-purr, a citizen ci the United States., and a resident ofthe city oit New lirork, Borough of Manhattan, in the county and State ot New York, have invented a new and improved Car Truck, oi which the following a i'ull, clear,y and exact description.

rlhis invention relates to rolling stock and particularly to what may he termed as articulated car sections and the trucks there-for and has for anv object to provide an improved arrangement of trucks which will properly support the car at all times and which will properly operate regardless oiE the curvature "oiz the track.

Another object oit the invention is to pro vide a jointed car oit novel structure wherein special arrangements are provided at each oi the end truck sections itor permitting ready turning action which will co-act with the central` or connecting truck section.

A. still further object of the invention is to provide an improved truck wherein a transverse member is provided tor holding suppmi'ting rollers in place and for properly supporting a car hody as the car hodytilts or movesup and down.

il.. still further object oi the invention is to provide in a Iiointed car an improved system ot rods and levers wherein the respective truck sections are positively held in correct position. on a straight or curved track so that each truck section will act eiiiciently.

Figure 8 is atop plan view showing in diagram slight modiied form oi' connecting rods and levers to that shown in Figure 1, one lend truck section and a central truck section being shown.

Figure 9 is view similar to Figure 8 lout showing another Jform of connecting rods and levers.

Figure 10 is a detail fragmentary view through Figure 1 approximately on line 10-10, the same being on an enlarged scale.

Figure 11 is a dia-gram showing how the truck sections are held when passing from a straight track toa curved track.

Figure 12 is a diagram showing the position. of the various axles ot the respective truck sections when the entire car is on a curve.

Referring to the accompanying drawings loy numeral, 1 and 2 indicate the respective sections of the body of the car, said car sections being supported by end truck sections 3 andeanda central truck section 5. The car sections 1 and 2 are articulated so that they are pivotally connected at adjacent points while thc opposite ends are allowed to freely swing with the truck sections 3 and fi; whereby the entire car may readily pass a straight 'track or a curved track having any desired curvature. The particular connection illustrated in the drawing between the car sections 1 and 2 is shown more or less in detail in Figure `1() wherein it will he seen that the car section 1 is provided with ears 6 and 7 while car section 2 1s provided with an ear 8 designed to loe inserted between ears (i and i whereby a pivotal pin 9 may loe readlare articulated and the articulation main tained at a central point in respect to the tramo 12 ot truck section 5. A straight rod '13 is pivotally connected at 14 to frame 12 and also pivotally connected to a bell crank lever 15 having arms 16 and 17. rlihe arm 16 is pivotally connected with a rod 18 which rod in turn ispivotally connected at 19 to limi lill@ the 'trame 2O of truck section |The pivotal connection jll is pre'l'erably al'` some point along' the rear har ol the 'trame 20 while the connection l/l is preferably a1' 'ringed centrally ol' the side bar of trame l2 oit' truck section A similar'arrangement olE levers and bars connect truck section 4- ivil'h truck section so that both the 'liront and rear truck se1-- tions are maintained at the proper angle in resoect to the truck section lt will be noted that the angle between rod 13 and arm l? is a lll) degree angle while the same angle is maintained between arm l@ and rod 1S. though these angles may be varied il: desired. rlhe car sections l and 2 are provided with a number of members or arms .21 in which the various rollers 22 are pivotally mounted, there being 'tour rollers and the rollers arrano'ed with their axles parallel to the axle 2?.) or the wheels 24 and 25. By this arrangement the various rollers 22 are ef;- tending transversely of the car sections. By this construction and arrangement oit rollers the car body is allowed a slight motion Ytor- Wardly and rearwardly and a slight side motion as itis started and stopped and moves around a curve.

llhe arrangement of the rollers acts as a 'tour point support 'tor the adjacent ends ot the car sections l and 2 while at the same time permits a ready and easy swinging movement of the respective sections at the same time or at different times.

' The truck sections 3 and 4lare constructed differently from truck section 5 but there two end truck sections are identical so that the description ot one will apply lo both. As shown particularly in Figures I3 and al the car section l is provided with longitudinal channel irons 2'? and in which the box 29 is mounted which bof; is provided with a depending hollow king pin 30 littinp; into av pivot member 3l, which pivot member is normally held centrally in a transverse sense by the springs 32 and acting on the pivot member 3l and on therespective angle .irons Se and riveted or otherwise rigidly secured'to the curved bar 36 oli' the Ytrame 20. rllhe pivot member J. is provided with depending lugs 37 and 38 having horizontal axles for receiving' rollers ande() which operate on suitable supporting; angle irons 4l and l2 rigidly secured to the cross bars 36. Rollers 43 and 44 are mounted on the upper part ot the pivot member 3]. and act against small angle. irons 45 and 46 also secured to the bars 36. By this construction and arrangement the king` pin il() may move laterally against the action olt the springs 32 and 33 guided and supported by the rollers 39 and 40. It will, of course, be understood that this movement amounts to only a short travel. The brackets lly and ft2yprevent any undesirable upward movement ot the parts so that the rollers lll :1nd lll may bc always in position to properly l'uiu'lion.

As shown in lfigruri-s 2 and fl lhe angle bars lli have what may be lernlod :l slirrup or socket member Al-,i' counerlcd llurolo :ulill cent each end. These sockel members are prelrrahly proridcd n'ilh enlarged porlions or l'langes lll whereby lhey maj: be readily riveted or otherwise secured lo lho hars Ilo. .in elliptical spring nlll is mounled on lbi` bottom ot e; .cli olt these sockets und urrizniljed so that the upper central parl; will engage they bottom plate oli ol' a bearing' member .'i which lil-turing' member rcrcires lhe zij-lo or bearing' pin 522 ot roller 553 which roller en enges one ot the rollers 2G. The :aides ol' lho hearinn member 5l extend any suilable di tance downwardly into u stir'i'up or r--iockcl member il'i' so as to be Iguided by lhe slirrup in its up and down movement, This :irrang'ement causes cach ot lhe rollers '53 lo be supported by a spring' and the rollers in turn support the rollers 2li 'which last nien tioned rollers support the car liody. .This arrangement olE support permils lthe sections oli' the ear body to vlireely more lalerully or swing' around the king' pin il() courting with thaA pivot meml'ler 3l and associated parts.

ln Figures 5, 5a. G and 'T will be seen a modified torni ol" the invention in which .-1 different arrangement is shown ol5 the slivrup or socket vl-" and associated parts illustrated in Figure 2. ln this arrangement ol these iig'ures there is pr nfifled a cross member or roller bnr :il which is l'ornicd wilh a vertical slot 55 centrally lhoreolt :reconnu-'idalingl' the |`fluide pin fili. which I:ruido pin if' carried in a lined position by lhe channel bars 3h. lllaeh end ol l'he roller bar is provided with a sockel, 5T in which lhc rospeclirc rollers 5Fl are mounted. said rollers being' mounted on suitable journal pins .so as to lireely rotate. said journal pins exlonding' transversely' ol lhc truck soclion. lxtendinv from caca socket 5T is :i spring engaging' lng' 59 through which lho rlanlping); bolls (ill extend. said clampingr boils clamp-- i the upper parl ot spring' lll in pluie `lhe lower parlol` the .spring` lll is clal'ied by o sritable llboll; Gl. ln this A are snpoorted by elliptical sifii'ing's totingtier terms ol spring' could be usec..

ln addition. it will be noted that the rollers :'53 are permitted an up and down movement in a similar manner lo lhe respective rollers 53. said movement beine; si multaneous vtor both rollers or alter-nale. The arrangement oit the slot 55 and pin .fill permits the har 54 to tilt so that one end will move down and the other up or swing in such a manner as l'o canso one end lo slay stationary and the other to more downwardly or as a third characteristic lo cause both ends to move downwardly substantially ll (l lllli lll) simultaneously. As the bar 54 rocks the socket members 58 move upwardly and downwardly usually on the arc of a `circle spect to each otherand the track.

but this are is so large and the movement is so small it is in effect a vertical. movement as tar as the roller 58 is concerned. Preferably, each socket member 57 is provided with guiding runners 62 which =guide the socket members in their movement. i

. nIn Figure 8 a slight modified form ot rigging is provided for holding the various truck sections at their proper'angle in re- It Will be noted that the rods 63 and 64 are connected on opposite sides to the truck sections 3 and 5 and extend to levers 66 and 67 pivotally mounted on suitable supporting pins 65 carried by the car sections and connected `together by a link 68. A similar arrangement `is made at the rear of the car for taking'care of the rear truck section l in respect to the front truck section 3 and center truck section 5.

i 1n Figure9 an additional arrangement of rigging is provided `vvherein the rods 63 and 641 are connectedto levers 69 and 70 which levers are pivotally` supported by suitable pin 69 carried bythe car sections at their opposite ends and connected centrally by link 71. y

1n Figures 11 and 12 vvill be seen diagrams showing the action of the rods and levers illustrated in Figure 1 when the truck is passing from a straight track to a curve or when the car is passing around a curve. In Figure 11 vvill be seen that the rear truck. section 4 is on the straight track and the axles extend at fright angles tothe track While the front truck section 3 is on a curve and theaxles extend slightly oilil of the line drawn norm al to either rail. The axle of the center truck section 5 is at a juncture o' the curve and the straight track, and` conse quently, is held so as to extend transversely in respect to the straight track.

In Figure 12 the 'lront and rear truck sections *3 and 4 assume the `same general posi tion `While the central `line through the axle of trucksection 5 is a radial line in respect `to the curve of the track. By reason of the construction and arrangement of levers the center truck section 5 will always act as a support for the articulated section of car body adjacent the ends regardless of the .curve on which the car operates.
